To aZZ whom, it may concern:

Be it known that I, BERNHARDT J ORGEN- SEN, a subject of the King of Denmark, re-

siding at Beverly, in the county of Essex and State of Massachusetts, have invented cert tain Improvements in Machines for Working Upper Over Lasts,.ofwhich the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indi-- eating like parts in the several: figures.

This invention relates to machines for use in the manufacture of boots and shoes for working uppers over lasts. In the manufacture of some kinds of shoes, such for example as one type of rubber-soled shoe commonly known as sneakers, it is the usual practice to secure the upper in conformity to the contour of the last by causing the margin of the upper to adhere to the insole, for example by the use of cement. An object of the invention is to provide animproved machine adapted for use in the manufacture of shoes of this type for working'the upper over the last and securing it, but it will be understood that-the invention is not limited in respect to utility to the manufacture of this particular kind of shoe nor. to the manufacture of shoes in which the soles or other parts are made of rubber.

Rubber-soled shoes of the kind abovementioned are usually made with a comparatively thin insole which is shaped from a rubber compound and which is not vulcanized until after the lasting operation on the shoe. During the operation of conforming the upper to the last the insole is in a comparatively soft and yielding condition, and for this reason it is necessary to avoid any action upon the shoe materials such as to wrinkle the insole or to displace it from the edge of the last. Because of this condition the operation of lasting shoes of this kind has been performed heretofore very largely by hand. a

This invention. provides a machine so constructed as to perform its operations upon the shoe without danger of displacement of the insole relatively to the last, the term insole being used herein as a generic term to indicate that part of the shoe to' which the upper is secured to hold it in conformity to the contour of the last irrespective of the type of the shoe. The invention is herein pulling-over means shownas embodied in a machine in which the means for working the upper over the last 'COIHPIISQSHIGELHS for pulling over the upper and means for lasting the 'forepart of the shoe, but in its venti'on is not limited to a combination of and lasting meansnor restricted withrespect to the portion of the shoe upon which the'operations may be performed. i i

A feature of the inventionconsists in a novel construction and arrangement of means for working an upper over last and for securing it to the insole by adhesion, the machine herein shown having overlayng means constructed to bend the margin of broader aspects the in the upper inward over the insole without substantial pressure against the insole such as would tend to displace it, and means for pressing the margin down into position to adhere to the insole. In the illustrative machine the overlaying means comprises members which are similar in construction and use to endembracing wipers of prior pulling-over and lasting machines, and for con.- venience these members will accordingly be referred to herein as wipers, although in the use of the present machine they are operated in such relation to, the shoe as to gather and bend the margin of the upper inward without substantial overlaying pressure. Combined with these overlaying members or wipers in the illustrative construction are presser members which are movable in paths transverse to the plane of the insole for engagement with that portion of the margin of the upper which projects farther inward than thewipers to press the margin against the insole, the construction shown having meansfor directing these members in paths which are inwardly inclined toward the shoebottom to cause them to engage the upper with a tendency, to pull it inward from the edge of the shoe and thus to eliminate any wrinkles and to tighten the upper on the last. a

in addition to the novel feature above set forth. the invention also presents novelty in the construction and arrangement of means for pressing the margin of the upper against the insole irrespective of other constructional features of the machine, and in a novel combination 'of different means including a roll or rolls for overlaying difi'erent adjacent portions of the margin of the upper.

The various features of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims.

' The machine herein shown'embodies in its general organization manyof the features of a type of machine shown and described in United States Letters Patent No. 1,280,613, granted on Oct. 2, 1918 upon an application of Orrell Ashton, to which reference maybe made for a more complete understanding of various details of the construction of machines of the illustrative type not hereinafter specifically described. The machine is provided with asole rest 2 against which the bottom of the insole on the last is positioned when the work is presented to the machine, and with a heel rest 1 which is moved automatically up into supporting engagement with the heel end of the shoe after the machine is started. For pulling the upper the machine includes a toe gripper 6 and side grippers .8 connected respectively to updraw levers 10 and 12 mountedon a pivot rod 1 1, the toe gripper lever 10 being operated yieldingly from a cam on a cam shaft 16 through a spring 18 and the side gripper levers 12 being similarly operated through springs 20. The pulling of the upper is effected by the operationof the gripper levers assisted by a slight downward swinging movement of the sole rest 2 effected by means of a cam 22 on the cam shaft 16,

the machine then coming to rest with the upper held under tension to permit the work to be inspected by the operator and any necessary adjustment of the upper on the last to be made, as for example by manipulation of the updraw levers 10 and 12. The

"machine is also provided with side clamp sure upon the shoebottom.

Similarly to the machine shown and described in the prior patent, above mentioned,

the machine herein shown is provided with wiper mechanism carried by a front arm 30 mounted to swing in directions lengthwise of the shoe, this mechanism comprising two sets of end embracing wipers adapted respectively to operate upon right and left shoes. The different wipers are mounted on opposite ends of a bracket 32 which is slotted lengthwise to permit limited relative movement of the wipers and the arm 30 in directions lengthwise of the shoe. A spring 34 (Fig. 1) mounted on a rod projecting downwardly from the end of the arm 30 through the slot in the bracket 32 tends to maintain the bracket in its adjusted relation to the arm while permitting the above-mentioned limited relative movement between the two parts andalso permitting the bracket to be swung about the end of the arm to position the wipers at eitherend of the bracket alternatively for operation upon a shoe.

Each set of wipers comprisesa pair of end plates 36 pivoted at 38 on a support 40 which is secured to the bracket 32. These plates are held normally in open position by means of springs 12, the limit of their opening movement being determined by engagementof pins 14: thereon with a plate 416 which is movably mounted on the support 40 and is adapted for use by the operator in positioning the wipers relatively to the shoe and in partially closing them in preparation for their advance over the shoe bottom. Pivotally mounted. on the plates 36 are extension members 18 which project beyond the ends of the plates 36 and serve as continuations of said. plates to operate upon portions of the upper at the sides of the toe and rearwardly along the forepart of the shoe. The connections between the extension members 18 and the plates 36 permit said members to swing a limited distance relatively to said plates." Operative movement of the wipers lengthwise of the shoe to cause the end plates 36 to perform their function at the end of the toe is effected by swinging movement of the. arm. 30, such movement being limited by engagement of an abutment' pad 31 on the bracket 32 with the end of the shoe. The closing movement of the wipers over the shoe is effected by means of side arms 50 which are similar to the side taclrer arms of the machine described in said Ashton patent and carry means which will be hereinafter described more in detail for engaging the extension Wiper members $53 and closing them inward over the shoe, andthrough the action of these members for closing also the end plates 36. Movement of the arms 50 toward the shoe is limited by the engagement of stop lugs 49 on the arms with abutment shoulders 51 on the sideclamp arms 24;

' The means for operating the arms 30 and 50 is the same as in prior pulling-over ma-,

chines of the illustrative type and, briefly described, comprises a slide (Figs. 1 and 5) connected at its tront end to the-arm 30 and connected also through segmental gears 54 to slides 56 which have operative connection with the side arms 50. Movement of the slide 52 in one direction thus serves 'to swing the arms toward the'shoe and its movement'inithe opposite direction to return the arms to starting position. The connection between the slide 5:2 and the arm 30 comprises spring plungers 58 at opposite sides of the arm which are carried by the slide 52 and have beveled faces to en gage similarly beveled abutment faces on the arm, these plungers being arranged to yield and permit the slide to continue its movement for a short distance after the arm 30 has arrived at its-limit of movement toward the shoe. For the same purpose the gears 5d are connected to the slides 56 through toothed slides 60 which carry spring plungers 62 having beveled faces to engage similar faces on the outer endsof the slides'56. This construction whereby the slides 52 and 60 are afforded limited movement relatively to the arms 30 and 50 serves to insure that the arms shall be advanced to their limit of movement irrespective of the size of the shoe, and also servesanother purpose which will be explained more fully" hereinafter.

F or pressing themargm of'the upper into position to adhere to the insole the front arm 30 carriesa presser member 64; which is curved similarly to the wipers and is constructed and arrangedto engage a section of the margin of the upper which projects inwardly beyond the inner edges of the in termediate portion of the wipers and press it into position to adhere to the insole. Preferably'the member 64 is provided with a pad 66 of leather or the like to insure effective and uniform contact with the upper material. The member (i l is secured to a pair of side platesTO which are in turn secured to slide 72 mounted in a slot '74- in the lowerend portion oi the arm 30 and pro vided at its upper end with a pin 76 engaged by the forked lower end of an operating bar '78. ward operative movement is imparted to the member 64rto cause it to press the margin of the upper into position to adhere to the insole. It will be noted that the guide slot Tl is inclined to the plane of the shoe bottom in such manner as to cause the member 64 to receive a component of inward movement 50 carry each. a pair of presser members 80 which, similarly to the member 6%, are arranged to engage a portion of the margin which projects beyond the inner edge of the wipers and press it into position to adhere to the insole. Similarly to the member G l, the members 80 are faced with a pad 82 of leather or the like, the construction shown comprising a single pad 82 secured to both members 80 of each pair. The members 80 are pivoted at 81 on the lower ends of sup porting bars 8 each of which is pivotally suspended at 86 on an arm 88 which is in turn pivoted at 90 on a carrier plate 92. The plates 92 are suspended on a pivot 9% carried by the arm 50 and are permitted to swing relatively to the arm about this pivot as a center a limited distance determined by a stop screw 96 which extends through slots 98 in the plates. Each of the bars 84carries apin 100 which engages in a slot 102 in the adjacent carrier plate 92, this construction serving to position the bar and the member 80 relatively to the plate 92 and to guide the member 80 in its operative movement toward the shoe. Springs 104 engaging the carrier plates 92 tend to swing them about their pivot 9a in the direction of the shoe, thegsprings yielding more or less as the plates engage the wipers or the sides of the shoe to permit the plates to adjust them selves to the lateral contour of the shoe and thus to position the presser members 80 at the correct distance from the edge'o'f the shoe bottom. Operative movement is imparted to the members St) from an operating bar 106 slidably mounted in the arm 50, this bar carrying pin 108 which engages in slots in the arms 88 and thus establishes an operative connection between the bar and the armswhile permitting the arms to move relatively to the pin and to each other in the adjusting movement of the plates 92. It will be understood that as the bar 106 is moved downward. the arms 88 are swung about their pivot 90 and force the bars 84 and the As the bar 78 is moved down presser members 80 downward toward the shoe. By reference to Figs. 2 and 3 it will be seen that the slots 102 are inclined in such relation to the shoe bottom as to cause the members 80, similarly to the end member 64, to engage the margin of the upper with a tendency to pull it inward and thus to tighten the upper on the last. It will be evidentthat the members 80 by reason ot their pivotal connection at 81 with the bars 84 are permitted to adjust themselves to the lengthwise contour of the shoe bottom.

It will be understood that-the bar 78 for operating the front presser member 64 and the bars 106 for operating the side presser members 80 are similar in construction and arrangement to the front and side tack driver bars of prior pulling-over machines, and since the mechanism for operating these bars is the same as in prior machines it will be described herein only briefly. Operative movement is imparted to the bar 78 by a lever arm 110 which is operated by a torsion spring 112, and similar movement is imparted to the side bars 106 by lever arms 114 operated by springs 116. Normally the bar 78 is upheld against the tension of its spring by means 01": a plate 118 (Fig. on the slide 52 which engages under ashoulder 120 on the bar 78. and the side bars 106 are similarly upheld by plates 122 on the slides 60 which engage under shoulders 124 on the bars. The operative movement of the slide 52, as hereinbei'ore explained, serves to swing the arms 30 and 50 inwardly toward the shoe, and during this swinging movement the arms continue to be upheld in the manner above described. When the arms, however, have reached their limits of movement and are stopped in the manner hereinbefore explained, the continued movement of the slides 52 and 60 serves to withdraw the plates 118 and 122 from the respective shoulders 120 and 124 on the bars 78 and 106 and thus to release the bars to their operating springs and permit them to be driven downwardly tooperate the presser members 64 and 80. Subsequently, in the return of the parts to starting position, the bars are uplifted again in consequence of an oscillating movement of the supporting bracket 126 in which the slides 52 and 60 are mounted accompanied by outward return movement of the slides. These operations are explained more in detail in prior United States Patent No. 663,777, R. F. McFeely, granted on December 11, 1900. p

In order to extend the lasting operation of the machine farther rearwardly on the shoe than the wipers and the presser members 80, each of the side arms 50 carries a roll 128 which is pivoted on a holder 130 slidably mounted in a guideway 132 in a bracket 134, this bracket being mounted on a pivot 136 on the arm 50. This construc-. tion permits relative movement of the arm 50 and the roll 128 toward or from the shoe. and also permits the roll to swing in directions transverse to the plane of the, shoe bottom; A plate 138 is forked at its lower end to engage in slots inthe slide 130 and also has bearing engagement with an upwardly extending arm of the bracket 134. Extending through said arm and also through the plate 138 is a bolt 140 which is fast on the supporting arm 50 and carries a spring 142 hearing at oneendon the plate 138 and at its other end on a nut on the end of the bolt. The spring 142 thus tends to force the plate 138 toward the bracket 134 and thereby to force the roll supporting slide 130 inwardly toward the shoe, and at the same time the spring and the plate act uponthe upwardly extending arm of the bracket 134 with a tendency to swing the bracket about its pivot 136 and thus to depress the "roll 128 relatively to the plane of the shoe bottom. In operation, the roll is carried into engagement with the shoeby the inwardly swinging movement of the arm .50 while the side grippers are still holding the upper under tension as shown in Fig. 4, and as the roll is held back by resistance of theupper, the arm 50 is permitted to continue itsmovement toward the shoe. The roll is carried first into engagement with a portion of the upper which is below the edge of the bottom of the in verted shoe, and as the movement of the arm 52continues the roll swings upwardly over the edge of theshoe bottom against the tension of the spring 142. When the grippers release the upper the spring 142 reacts and forces the roll inwardly across the margin of the upper, as illustrated by Fig. 3. A substantial extent of the margin of the upper beyond the ends of the wipers is thus overlaid and pressed into position to adhere to the insole.

1n theoperation of the machineupon a shoe such, for example, as a rubber soled shoe of thecharacter hereinbefore described, the operator presents in the usual pulling over position, as indicated in Fig. 1, a last having assembled thereon an insole a of unvulcanizedrubber compound and an upper 2) of canvas or similar fabric, the margin of the upper having been previously coated with cement. The operator then depresses the starting treadle of the machine, whereupon the grippers 6 and 8 seize the margin of the upper and pullit upwardly in unison with a slight downward rocking movement of 'thesole rest 2 and by an upward movementof the heel rest 4 intosupporting engagement with the rear end of the shoe. The machine now comes to rest with the upper held under tension to enable the operator to inspect the work and make any of the usual adjustments which may be necessary. in some machines of the illus trative type all the subsequent operations upon the shoe are performed upon the second depression of the starting treadle, while in others the second depression of the treadle is followed only by the inward movement of the clamp arms 24: into holding and supporting relation to the shoe. While it is practically immaterial to the present inven tion whether the machine operates thus in two stages or in three, it will. be assumed for the purposes of explanation that the machine operates in three stages and that after the side clamp arms have been swung 'into operative relation to shoe, as shown in Fig. 2, the machine again comes to rest.

In the interval prior to the final depression of the starting treadle the operator, by s iding the bracket 32 forwardly on the low er end of the front arm 30 and by tipping the bracket relatively to the arm against the tension of the spring 34, positions the wipers in the relation'to the work which it is desired that they shall assume prior to their power effected operative movement. In operating upon a shoe of the character described the wipers will be so positioned as to afford substantial clearance, between them and the plane of the insole, in order to avoid displacement of the margin of the insole relatively to the lastthrough pressure of the wipers. Having positioned the wipers in the manner desired and closed them against the upstanding margin of the upper by manipulation of the plate 46, the operator, by manipulating a handle 144: on the toe gripper lever 10, opens the gripper and causes it to release the margin of the upper. He then depresses the starting treadle to cause the machine to complete its operation upon the shoe. 7

As the arms 30 and are swung inward in the final stage of the cycle of operations in the manner hereinbefore described, the wipers are advanced lengthwise of theshoe by the action of the arm 30 upon the bracket 32 to the limit determined by engagement of the abutment pad 31 with the end of the shoe. and the middle wiper plates 36 are thus rendered effective to bend the margin of the upper inward over the insole at the end of the shoe without substantial pressure against the insole such as mighttend to displace it. Simultaneously the carrier plates 92 on the arms 50 engage the extension wiper members e 8 and swing these members inward to bend the margin of the upper over the insole at the sides of the forepart, the members 48 through their engagement with the plates 36 serving also to swing these plates inward about their pivots 38. The carrier plates 92 by their engagement with the wipers and subsequently with the sides of the shoe adjust themselves against the tension of their springs 104 in accordance-with thelateral contour of the shoe and thus position the presser members 80 at the desired distance from the edge of the shoe bottom, the member 64: being similarly positioned by the movement of the front arm 30. arms '50 are swung inward they carry the rolls 128 into engagement with the tensioned upper, as shown in Fig. 4. Before the arms 50 have completed their inward movement they engage tripping devices 146 on the side grippers 8 and thus cause these grippers to release the upper, whereupon the rolls 128 are forced farther inward by the action of the springs 142 and by the continued move ment of the arms 50 and press a portion of the margin or the upper which extends rearwardly beyond the ends of the wipers into position to adhere throughout its width to the insole. As soon as the arms 30and 50 have arrived at their limits of inward movement, the operating bars 7 8 and 106 are released to the action of their springs in the manner hereinbefore explained and in their downward movement carry the presser members 64 and 80 into engagement with that portion of the margin of the upper which extends inwardly beyond the inner edge of the wipers. The presser members, as hereinbefore eXplained,-. approach the shoe in paths which are inwardly inclinedtoward the plane of the insole, and in consequence of such movement they engage the margin of the upper with a tendency to pull it inward from the edge of the last bottom as well as to press it into adhering relation to the insole and thus assist in flattening the upper under the wipers against the insole and in pulling it tightly over the last. Subsequently to this operation of the presser members the parts of the machine are returned to their starting positions and the shoe is released from the machine. Inconsequence of the operation of the machine the forepart of the shoe is lasted and the margin of the upper is pressed evenly into adhering relation to the insole around thetoe and along the opposite sides of the forepart, as indicated in Fig. 7 j

The combination of upper pulling means and means for rolling the margin of the upper inwardly over the insole, in its broader aspects, is not claimed herein, since it is the prior invention of W. G.
